During VF load, prior to sending messages on HW channel to PF the VF
checks its bulletin board to see whether the PF indicated it has closed;
If a closed PF is encountered, the VF skips sending the message.
Due to incorrect return values, there's a possible scenario in which the VF
finishes loading "successfully", while the PF hasn't actually fully configured
FW/HW for the VFs supposed configuration.
Once VF tries to send Tx packets, HW will raise an attention (and FW possibly
will start treat the VF as malicious).

There was a bug in xennet_alloc_rx_buffers, when allocating page or
sk_buff failed, and at the same time rx_batch queue not empty,
the rx_refill_timer timer won't be scheduled. If finally the remaining
request buffers in rx ring less than what backend driver expected,
the backend driver would think of rx ring as full and start dropping packets.
In such situation, there is no way for the netfront driver to recover
automatically, so that the device can not work properly.
The patch fixes the problem by always scheduling rx_refill_timer timer when
alloc_page or __netdev_alloc_skb fails, no matter whether rx_batch queue is
empty or not. It ensures that the rx ring request buffers will finally meet
the backend needs.

For performance reasons, sch_fq tried hard to not setup timers for every
sent packet, using a quantum based heuristic : A delay is setup only if
the flow exhausted its credit.
Problem is that application limited flows can refill their credit
for every queued packet, and they can evade pacing.
This problem can also be triggered when TCP flows use small MSS values,
as TSO auto sizing builds packets that are smaller than the default fq
quantum (3028 bytes)
This patch adds a 40 ms delay to guard flow credit refill.

macvlan: disable LRO on lowerdev instead of a macvlan
A customer of ours encountered a problem with LRO on an ixgbe network
card. Analysis showed that it was a known conflict of forwarding and LRO
but the forwarding was enabled in an LXC container where only a macvlan
was, not the ethernet device itself.
I believe the solution is exactly the same as what we do for "normal"
(802.1q) VLAN devices: if dev_disable_lro() is called for such device,
LRO is disabled on the underlying "real" device instead.

- IPv6 forwarding is enabled for it
- it is in a different namespace than lowerdev and IPv4
forwarding is enabled in it
we need to disable LRO on its underlying device instead (as we
do for 802.1q VLAN devices).

If priority/traffic class field in IPv6 header is set (seen when
using ssh), the uncompression sets the TC and Flow fields incorrectly.
Example:
This is IPv6 header of a sent packet. Note the priority/TC (=1) in
the first byte.
00000000: 61 00 00 00 00 2c 06 40 fe 80 00 00 00 00 00 00
00000010: 02 02 72 ff fe c6 42 10 fe 80 00 00 00 00 00 00
00000020: 02 1e ab ff fe 4c 52 57
This gets compressed like this in the sending side
00000000: 72 31 04 06 02 1e ab ff fe 4c 52 57 ec c2 00 16
00000010: aa 2d fe 92 86 4e be c6 ....
In the receiving end, the packet gets uncompressed to this
IPv6 header
00000000: 60 06 06 02 00 2a 1e 40 fe 80 00 00 00 00 00 00
00000010: 02 02 72 ff fe c6 42 10 fe 80 00 00 00 00 00 00
00000020: ab ff fe 4c 52 57 ec c2
First four bytes are set incorrectly and we have also lost
two bytes from destination address.
The fix is to switch the case values in switch statement
when checking the TC field.

Commit 2613af0ed1 ("virtio_net: migrate mergeable rx buffers to page
frag allocators") changed the mergeable receive buffer size from PAGE_SIZE
to MTU-size. However, the merge buffer size does not take into account the
size of the virtio-net header. Consequently, packets that are MTU-size
will take two buffers intead of one (to store the virtio-net header),
substantially decreasing the throughput of MTU-size traffic due to TCP
window / SKB truesize effects.
This commit changes the mergeable buffer size to include the virtio-net
header. The buffer size is cacheline-aligned because skb_page_frag_refill
will not automatically align the requested size.
Benchmarks taken from an average of 5 netperf 30-second TCP_STREAM runs
between two QEMU VMs on a single physical machine. Each VM has two VCPUs and
vhost enabled. All VMs and vhost threads run in a single 4 CPU cgroup
cpuset, using cgroups to ensure that other processes in the system will not
be scheduled on the benchmark CPUs. Transmit offloads and mergeable receive
buffers are enabled, but guest_tso4 / guest_csum are explicitly disabled to
force MTU-sized packets on the receiver.

In af3e095a1f, Erik Jacobsen fixed one type of unaligned access
bug for ia64 by converting a 64-bit write to use put_unaligned().
Unfortunately, since gcc will convert a short memset() to a series
of appropriately-aligned stores, the problem is now visible again
on tilegx, where the memset that zeros out proc_event is converted
to three 64-bit stores, causing an unaligned access panic.
A better fix for the original problem is to ensure that proc_event
is aligned to 8 bytes here. We can do that relatively easily by
arranging to start the struct cn_msg aligned to 8 bytes and then
offset by 4 bytes. Doing so means that the immediately following
proc_event structure is then correctly aligned to 8 bytes.
The result is that the memset() stores are now aligned, and as an
added benefit, we can remove the put_unaligned() calls in the code.
